How to make matcha,
step by step.

A whisked bowl of ceremonial matcha takes about ninety seconds. Everything that goes wrong with it goes wrong in the first thirty.

Most home matcha tastes worse than it should for one of three reasons: the water is too hot, the powder wasn't sifted, or the whisk motion is wrong. Fix those three and a decent tin becomes a good bowl. Below is the method for usucha (thin tea), the everyday preparation, followed by koicha and the latte variant.

What you'll need

A chawan — a wide tea bowl. A cereal bowl works in a pinch; a mug does not (the whisk can't move freely).
A chasen — a bamboo whisk with 80–120 tines. This is not optional. A milk frother produces foam but doesn't emulsify the powder; you'll drink powder settling on your tongue.
A sifter — a small fine-mesh strainer. Matcha clumps in the tin; unsifted, those clumps hit the water and never dissolve.
A chashaku or a small measuring spoon — a bamboo scoop that delivers ~1 g per level scoop. Not essential; a half teaspoon works.
A thermometer or a kettle with variable temperature. Water off the boil is the biggest single mistake in home matcha.

Step by step: usucha

Pre-warm the bowl. Pour hot water into the chawan, swirl, and discard. Dip the tines of the chasen for ten seconds to soften them, then set aside. Wipe the bowl dry.
Sift 1–2 g of matcha into the bowl. Use the back of a spoon to press any lumps through the mesh. Roughly ½ to 1 level teaspoon.
Add 60–70 ml of water at 70–80 °C (158–176 °F). Boiling water scorches matcha and turns it bitter and thin. If you don't have a variable kettle, boil, then let the water sit for about ninety seconds before pouring.
Whisk in a "W" or "M" motion for about fifteen seconds. Keep the wrist loose and the whisk mostly on the surface. The goal is not to spin the water — it's to shear the powder into the liquid until a fine, even crema forms across the top.
Lift the whisk up through the foam in a slow spiral to smooth the surface, and drink immediately. Matcha separates within a minute or two; it doesn't hold.

Usucha vs koicha

Usucha ("thin tea") is the everyday preparation described above — 1–2 g of matcha to 60–70 ml of water, whisked to a foam.Koicha ("thick tea") uses roughly twice the powder and half the water — about 4 g to 30–40 ml — and is kneaded rather than whisked, in a slow figure-eight, until it takes on the consistency of thin paint. Koicha is reserved for the highest ceremonial-grade leaf because there's nowhere to hide; a mediocre matcha in koicha form is undrinkable. Try it once you're comfortable with usucha and want to see what the leaf actually tastes like at full concentration.

The latte method

Home matcha lattes taste chalky when the powder is dumped straight into milk. Dairy and plant milks are too thick to shear the powder the way water does. The fix is the same fifteen-second whisk step, first.

Sift 2 g of matcha into a chawan or wide cup.
Add about 30 ml of water at 70–80 °C and whisk in a "W" motion until fully emulsified — a small, thick pool of foam.
Steam or heat 180–240 ml of milk (dairy, oat, or barista-blend oat is best for foam), and pour it over the matcha shot. Sweeten separately if you want to; matcha reacts poorly with syrups added directly to the powder.

For iced, whisk the matcha shot with cold-brew-cold water in a jar, shake, and pour over milk and ice. Same principle: shear the powder into water first.

Common mistakes

Boiling water. The number one mistake. If your matcha tastes bitter, it's probably the temperature, not the tea.
Skipping the sift. Clumped powder never fully integrates and leaves grit at the bottom of the bowl.
Spinning the whisk in a circle. A circular motion just moves water around. The W/M motion shears the powder against the tines. Sound matters — you should hear it.
Using culinary-grade in a bowl. No technique fixes a wrong-grade leaf; see ceremonial vs culinary matcha.
Storing the tin near the stove. Heat, air, and light kill matcha in that order. Cool, sealed, dark.
